QN80F is a representative of the Neo QLED series, meaning it is a television with Mini LED backlighting. Unlike its cheaper cousin, the QN70F model, the diodes here are placed directly behind the panel (rather than at the edges), which gives it a solid advantage right from the start when it comes to contrast control. In the 65-inch variant we tested, we counted 88 dimming zones – a result that may not be particularly impressive, but as it turned out, sufficient to achieve quite decent results.
In tests based on scenes from films such as Oblivion and The Meg, the QN80F performed well – blacks were deep, and the overall image consistency was visually appealing. However, in more demanding moments (e.g., scenes with a large number of bright details on a dark background), a halo effect appeared. This is where the limitation of the number of zones becomes evident – bright elements could bleed into one another, and some details in the dark areas lost visibility. In one scene featuring a helicopter (The Meg), we even noticed slight brightness flickering, as if the television was trying its best to maintain detail visibility at the expense of black depth.
However, these issues are not exclusive to this model – halo effects or drops in contrast during very complex scenes are challenges faced by most Mini LED televisions, even the more expensive ones. In its class, the QN80F performs positively and offers significantly better contrast than the QN70F model with edge backlighting. For most users, this will be a level more than sufficient – although not perfect.
The NanoCell series, including the model NANO81 we tested, is based on an IPS panel. For anyone who is somewhat familiar with screen technology, this means one thing: significant problems with black levels and contrast. Our measurements are merciless in this regard. A result of 800:1 is, to put it bluntly, a tragic outcome. In practice, this means that what should appear on the screen as deep black looks like a dark grey patch at night. Watching dark films or series in a completely dark room will be downright torturous – the image will lose all its depth and appear flat. If you do decide on this model, we have one key piece of advice for you: do not watch it in complete darkness. To salvage the situation somewhat, it is best to leave a gentle light on in the room, and the ideal solution would be to install LED strips behind the television. Such backlighting will trick your eye (this is known as simultaneous contrast) and make that grey on the screen seem a little darker. Nevertheless, the start of the test for cinematic experiences looks bleak.
